I have windows 7 home premium 64 bit on my desktop. Desktop is 1 month old. Suddenly I can´t install programs no more. Spybot Search and Destroy says Error numer 5 "Can´t create temp folder in C:User/nameofuser...temp"
CCleaner setup says: Can´t create temp file. Make sure your temp folder is valid
Java Update complains about windows installer beeing not accessible.
All paths seem to be normal. I have admin rights. The paths in the registry - as far as I found them are the same as in the explorer. Automatic updates are activated.
Avira shows no viruses.
Who can help?
