If you're having problems getting the installer exe file for Photoshop 7 to launch, try these two workarounds.
1. Open up Windows in Safe Mode and then run the installer file.
OR
OR
2. The resources held by other processes might be stopping the .exe file from running. On my computer it was an HP resource.
To work out what is "blocking" the installer:
- Start Task manager, you'll see the setup.exe running as a background process.
- Click on the "Details" tab in the task manager
- Go down to setup.exe, then right click on it and select "Analyse wait chain" to view the string
- Select to close the program / end the process which setup is waiting on which should then launch the .exe file!
