Windows 7: trying to install Avast Free 5.0.677

I've been trying to install Avast Free 5.0.677 on Windows 7 x64 and keep getting :

"error 82 (00000052) has occured. Last performed operation was extracting main exe"

Windows Error 0x00000052 - 82
ERROR_CANNOT_MAKE
The directory or file cannot be created.

I wondered if this had anything to do with moving the TEMP and TMP folders off my SSD Drive C:\ and onto the Hard Drive F:\

I've not had problems like this installing any other software.

Anyone have any ideas?

Move the folders back, reboot and try to install again. Then you'll know if it is or not.

Thanks Airbot

Your advice was sound and once I returned the TEMP directory to the C:\Users\User\Name\AppData\Local\Temp folder I was able to install Avast. The nice little lady even told me the Virus Database had been updated.

The only problem was that I want to reduce the number of writes to my SSD so I was not happy with the TEMP and TMP folders being on C:\. After a bit of trial and error I found the best way to do this and still be able to use AVAST was:

1. Use Link Shell Extension to move C:\Users\Raider\AppData\Local\Temp off the C Drive (see here for instructions)

2. Install AVAST! on a Hard Drive (say D)

3. Use Link Shell Extension to move C:\ProgramData\Alwil Software to a Hard Drive.

This cuts the AvastSvc.exe writes to C drive considerably. There are still a lot of 4.096 byte writes going to C:\Windows\System32\config\SYSTEM but I don't want to mess with these!
