"Invalid filename" error while launching Retail Pro 9

Problem

When launching Retail Pro 9, you receive an error that reads, "Invalid filename", as shown below:

This error message may result from a permission issue with the Windows user. Specifically, that the logged-in Windows user does not have permission to write to the TMP location.

Solution

If you see this error, check the TMP location (as shown below).

1. Select the Start Menu > Run

2. Enter "%temp%" into Run menu, and execute

Note: The TMP path is typically C:\Users\\AppData\Local\Temp.

3. Check the folder and see if there is a "repository.dat" file.

If there is,?rename it and try launch Retail Pro again. A new file should be generated in the TMP folder.

If there is not,?the user currently logged-in likely does not the have proper permission to write to that location. Therefore, this user needs to be granted full access to that folder in order to resolve the issue.
