Issue with Hamachi installation

I've been searching for a solution for a few days now, I've browsed through countless of threads everywhere, and no one seems to have the same problem as me. I've even searched through all Hamachi related threads on the Swedish tech forum I daily visit.

So here's the deal; about 1 year ago I uninstalled Hamachi from my computer (don't ask me why) and lately I wanted to get it again. So I downloaded the hamachi.msi installer from the LogMeIn website, ran it; and got the message that an older version had been found on the computer and asked if I wanted to update it. I clicked no, which caused the installation to turn off completely, I started it again and clicked yes this time, which caused it to proceed with 5/6 of the installation before shutting down and giving me the message saying that it couldn't be installed and that no changes had been made to my system.

After this, I started googling around, I found that if you deleted all logs and registry entries connected directly to hamachi it would work. But as always when it comes to me and software, it didn't. Now, when I try to install it gives me the message; "LogMeIn Hamachi Version [PREVIOUSVERSION] has been on your computer. Would you like to proceed with an update?". Just like the last time, when you click no it shuts down completely, and when you click yes you get the message saying that it couldn't be installed and that no changes has been made to the system.

Here's a guy who seems to have the same problem with his Hamachi installation, but his solution doesn't work for me: http://forums.techguy.org/all-other-software/1009134-logmein-hamachi-installer-error.html

A little offtopic.. How do you change the text so that 10% of it doesn't randomly get reduced to a small font?

Try full UNINSTALL, reboot and then install fresh copy

I'm guessing you mean a full uninstall of windows?
So there are no simpler means of solving the problem?

Obviously, the previous version has not been fully uninstalled. Try Revo Uninstaller Pro which in my experience has best chances for a full job. Follow the procedure for forced uninstall. If you don't want to buy it, you can get it on a free trial.

Ah well, I thought people would understand that it's already uninstalled since I even cleaned the registry of it, but nvm, my mistake.

As BobCat posted. You might want to try this program, (Revo). Just because it is out of the registry. Dose not mean it is already uninstalled. It could have left a few files. Which very well be causing your problems.

I ran the forced uninstall tool with the keyword LogMeIn Hamachi and found 10 files, removed all of them, rebooted, still the same error. After the reboot and failed attempt to install I ran the tool again and found no files. Any other ideas?

My guess there is still something in there pertaining to the program. Where at hard to say. You may have to do a manual search for a dill or file.

How thorough should I be? I've looked everywhere but in the windows folders and I've found nothing so far.

There may be a hidden file. Other then that I can not think of anything else at this time. Hopefully someone else may have a good suggestion.

I know you said you have uninstalled the application and that may render this tip obsolete, but it could be worth a quick look; Check your Network Connections/Adapters and see if Hamachi's virtual adapter is still there. I've had an issue in the past uninstalling Hamachi where I couldn't get it to properly uninstall until I went and manually disabled the network adapter. You also might want to check to make sure there are no active services installed/running and that the Hamachi drivers have all been uninstalled in Device Manager (Should be under Network Adapters) as they could prevent a proper uninstall/reinstall.

If you're still hitting a wall, you could try turning on Windows Installer Logging, which will log the progress of program installations (Specifically .msi). This may give you a better idea of where to go next. For instructions on how to turn on Windows Installer Logging, go here: http://support.microsoft.com/kb/223300#letmefixit

This is a shot in the dark but worth a try..... Logmein uses the Windows Installer. So, use Windows Group Policy to enable Windows Installer logging. Then try again and look through the Installer log file. Maybe it'll leave a hint of what's going on

1. Click Start->Run, enter gpedit.msc. The Local Group Policy editor should open
2. Under Computer Config click Admin Templates->Windows components->Windows Installer
3. Then in right pane, double click Logging. Activate all the logging options.

/* Edit */
just realized someone above also mentioned Installer logging. Tho easiest/best to use the Group Policy editor for Win 7

Good luck. Hope it might show something useful

You can also use "Process Monitor" to see which files and registry keys are being accessed by the install so you will directly see where it hits.

Apparently "run" can't find gpedit.msc, I've also tried to delete the virtual adapter; which didn't work.

Most likely you're running Windows 7 Home or Starter which don't include the Local Group Policy editor. While a bit more tricky, you should still be able to activate Windows Installer Logging from the registry (See my previous post).

When you say that you've tried to delete the virtual adapter, does that mean that the Hamachi adapter shows up the Network Connections and/or Device Manager? If you still see it in Network Connections, try finding the adapter in Device Manager under Network Adapters. It should be called Hamachi-something-or-other. You should be able to right click on it and select Uninstall (If it gives you an error about it being in use or something, try doing it in safe mode without networking enabled). If you're able to do all that, then I would try reinstalling it again and see if you can get it to go. If not, try the Windows Installer Logging and see if that can shine a little light on things.

Also, it appears that Hamachi dumps an install log of its own in the temp folder (Type in %temp% in the start menu). I don't know if it will still dump the log if the installation failed, but it may be worth looking into.

Oh, I've already removed it from the Device Manager, that's kind of what I meant . And now that you mention it, it has been a while since I cleaned the temp folder, I found 1.84 GB of crap in it.. Gonna see if this solves anything.

I created that Installer key and set the value of the Reg_SZ to voicewarmupx as the guide told me to. After that I ran the installation, but I can't seem to find the log file.

Hmmm... it should be in the temp folder (%temp% again) under a randomly generated name. For instance, the one generated for me was called MSIfeb8a.LOG, but they should always start with "msi" and should always end in .log.

If you can't find that, try finding the Hamachi installer log also located in the temp folder (Should be called HamachiSetup.log) and take a look inside. You could post the contents of the log as well if you're comfortable with that and it's not too lengthy.

*Edit*
An obscure question that may yield some results; Do you happen to remember what version of Hamachi you had installed in the past? Do you know if it was Version 1 or Version 2?

I have no idea which version, but I know it was a fresh download sometime during the late summer of 2011.

As for the log files, I found the log files in the specified folder. Two of them said the same thing the error message says when you're done with 5/6 of the installation;"the older version of hamachi cannot be removed, please contact your technical support group".

I've tried installing in both swedish and english, both seems to end with the same thing.
