The post described the steps I took.....see above.
Photoshop opens and operates fine. Just didn't install update. Says 'this installer is misconfigured' and to contact program author. Adobe website no help.
Like I said, I can still use the program, just wanted the critical update.
Thank you for your help, suggesting the C:\Program Files(86). Will try that.
Try resetting the preferences also
1. Close Elements.
2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Edit.
3. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file; click Yes. Elements will open with default preferences.
