I cannot install the new Training Gym v 2.0 software on Vista Professional. The install always fails with the following message:
"The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2869"
When I OK this, I get two further blank dialog boxes with just an OK button (no message), then the installation rolls back and I get a message saying the installation was interrupted before it could be completed.
From doing a bit of googling, this message seems to be associated with permissions associated with CustomActions in MSI packages on Vista, but I've tried the recommended solutions, such as running 'msiexec /i GS-Sport Training Gym.msi' from a command line prompt as Admin, without success. The strange thing is that this is a failed reinstall - it originally installed OK but I needed to reinstall it.
What is the problem, please, and how can I get the software installed?
