Troubleshoot error messages in Bootstrapper CS5, CS5.5

Bootstrapper CS5 loads the Adobe Creative Suite 5 or CS5.5 product installer. It detects conditions on your computer that can cause installation problems or failures and presents error messages for them. Follow the instructions to troubleshoot the errors.

A restart is pending (Windows)

If you receive the error, "Installer has detected that a machine restart is pending. It is recommended that you quit the installer, restart try again," do the following:

  1. Restart the computer and try the installation again.
  2. If the installation fails, delete the InProgress registry key:

Disclaimer: This procedure involves editing the Windows registry. Adobe doesn't provide support for editing the registry, which contains critical system and application information. Make sure to back up the registry before editing it. For more information about the registry, see Windows registry information for advanced users on the Microsoft support site, or contact Microsoft. 

  1. Launch Windows Registry Editor.

Insufficient hard disk space

Bootstrapper requires at least 100 MB of space on the startup drive. Additional space is necessary for shared components. Bootstrapper needs this space to copy installation files to one of the following temporary folders:

  • (Windows XP) \Documents and Settings\[user name]\Application Data\Adobe\OOBE
  • (Windows Vista/Windows 7) \Users\[user name]\AppData\Local\Adobe\OOBE
  • (Mac OS X)  ~/Applications/Adobe/OOBE
  1. Delete files so that you have enough hard disk space.
  2. Click Retry.
