Argghhh.. I feel your frustration! But I'm glad you thought to copy/paste the instructions from Logitech because I see their instructions include a critical but poorly written sentence
/* EDIT */
Ooops.
* So it rebooted and I set things at normal setup and I am still not able to read my own minidump even though I am the administrator.
After re-reading your post, i think you did, in fact, do things in the order as intended. My original post continues below - though now not sure that it really applies for you. In any case, will follow-up with more sometime later
/* End of Edit */
When Logitech says "After performing the necessary steps," they mean "now is the time you should try to reinstall your webcam". So, if i read your post as being in the sequence you did things(?), then you retried the Logitech install AFTER you restored your boot settings
Try this (and make sure you already have the Logitech downloaded install file)
First part of Logitech Instructions
1. Click Start --> Run --> Type MSCONFIG --> Click OK
2. On the General tab, choose Selective Startup
3. Uncheck Process SYSTEM.INI file
4. Uncheck Process WIN.INI file
5. Uncheck Load Startup Items
6. Click on the Services tab
7. At the bottom, check Hide All Microsoft Services
8. Uncheck all boxes in the window or click the button labeled Disable All
6. Click OK
7. Click Restart
Add these steps here
On restart, click OK , OK , Exit without Restart to the pop ups you'll see. Then
1. Open Add/Remove Programs. Look for the Logitech webcam (i think it should be in there now). Uninstall it. Does it uninstall without problem?
2. Open MS Installer cleanup tool and check again logitech isn't there
3. NOW, run the Logitech installer. Does it run OK or still BSOD?
Now we resume Logitech instructions to restore your system by doing the following:
1. Click Start --> Run --> Type MSCONFIG--> Click OK
2. On the General tab, choose Normal Startup
3. Click OK
4. Click YES, when asked to restart your computer
