Photshop Scripting 1.0.2a instal error

For Photshop 7 you must install the scripting additions. I am getting the following error from the Vise ‘Photoshop Scripting Support’ installer:

Error creating file
1008:5, -5000 Access denied error

Scripting Support is not compatible with PhotoScripter. To ensure that Scripting Support operates correctly, you must uninstall PhotoScripter first by removing the PhotoScripter plug-in from the Photoshop Plug-Ins folder.

Using OS 10.2.8 with the latest patches and I do not have PhotoScripter installed.

Has anyone else had this error?
Is there a fix, other than upgrading to CS?

Thanks. :idea:
