Can´t install programs - either no access to temp folder or windows installer denies service depends on program to install


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?

Hi Eiergeier 1,


I would suggest you to try the following steps:


Users experiencing similar problem have fixed this issue by starting “Windows Installer Service”, I would suggest you to start the service and check if the issue persists


Step 1: Make sure “Windows installer” Service is set to automatic and started. To do this, follow these steps:

1.    Click on Start-Run, type services.msc, the click on OK.

2.    When the Services window loads, navigate to the " Windows installer Service", the double click on it to open it,

3.    Make sure the "Startup Type" says "Automatic" and started. If it doesn't, use the drop down menu to change it.

4.    If it already says: "Automatic", then click on the "Recovery" tab at the top, and change the "First Failure" line to "Restart the Service", then click on "apply", then OK.


Step 2: Check with another user profile

If you do not have another user account, you will have to create one (see the link below).  If everything works fine with another user profile, you can infer that the user profile is corrupt, check the link to know how to fix this issue.
