Adobe Reader 8 Fails to Install on Windows Vista

Solutions to resolve the problem

Although one of the core aspects of Adobe Reader 8 was the support for Windows Vista, in reality, installing Adobe's software on Microsoft's latest operating system generated multiple issues resulted in failed installations.

Adobe System has confirmed a case of Adobe Reader 8 installation failure that displays the following error message: "The Temp folder is on a drive that is full or is inaccessible. Free up space on the drive or verify that you have write permission on the Temp folder." According to Adobe, this issue is related to the fact that the User Account Control in Vista is turned off, or the user has only default administrator level privileges. In both cases, Windows Vista cannot access or write the %TEMP% folder.

Here are the resolves provided by Adobe Systems:

Solution 1: Enable User Account Control.

1. In Control Panels, choose User Accounts.

2. Click "Turn User Account Control on or off".

3. Check the box to "Use User Account Control (UAC) to help protect your computer" and then click OK.

4. Restart your computer.

5. Install Adobe reader 8.

This time, Vista's Windows Installer displays this error message: "The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance." In this case, there is an altogether different workaround:

2. Open explorer and copy the "Adobe Reader 8" directory from the following path to your root dir

"C:Users{username}AppDataLocalLowNetopsystems emp"

3. Run the setup.exe from the "Adobe Reader 8" directory on your root dir.
