TortoiseSVN The coolest Interface to (Sub)Version Control

Several error messages are combined in this FAQ. If you find another one, and a solution for it, please let us know.

Note: as of TSVN 1.2.0, Windows 95/98/ME and Windows NT4.0 are no longer supported.

• "This installation package is not supported by this processor type. Contact your product vendor."
  This means you are trying to install the 64-bit version of TortoiseSVN on a normal 32-bit operating system. You need to download and use the correct msi file for your OS. For normal 32-bit OS, make sure the msi file does not have an x64 in it.
• "The installer was interrupted before TortoiseSVN could be installed. You need to restart the installer to try again"
  Then the user SYSTEM doesn't have read/execution rights in the folder where
  the installer msi is located. Either move the msi file to another
  location or give the user SYSTEM read and execution rights.
• "The windows installer service could not be accessed"
  This can occur if you are running Windows in safe mode, or if the windows installer is not correctly installed.
  For this kind of error message, please check out the Microsoft Knowledgebase article Q315346 (basically, check that the folder where the msi is stored isn't encrypted or compressed)
• "The system can not open the device of file specified", followed usually by "The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755".
  This can happen if:
  • The installation does not have access to the Temp directory or if the default Temp directory of the machine is not clean or does not have enough space to run the setup.
  • The installation is being run over a terminal Server via a mapped network drive.
  • The installation is unable to create or write to the Installer directory in a Windows NT system environment.

  To solve this problem, clear the temp folder, move the installer msi file to your local harddrive where the user SYSTEM has full access rights.
