I purchased an online upgrade to 2006. It downloaded but install failed: error message received and instructions followed. It happened again. I contacted support and gave them remote access to my computer to check for problems and install the software. The install froze at initialization. Re-contacted support and they suggested I had a virus and that I reboot the computer. I did that. Everything slowed waaaaaaaaaay down. Contacted support. They said to run a remote virus scan from their website. Couldn't access the internet---no more connection in windows xp. Contacted support. Had to be a problem with the ISP---no, there was now no connection in windows. Insisted it was an ISP problem. ISP checked and everything fine. Contacted support. Insisted I do remote scan through internet. Couldn't. Tried to make new network connection. Message: insufficient memory. Contacted support. They couldn't help until I connected to the internet and ran a virus scan. Contacted a repair contracter, who came and scanned the computer for viruses, found none, but XP corrupted sufficiently that had to do a clean install. Bill = $171CDN. Contacted support. Refunded $ for product, waiting to hear about restitution for repair.
