Error: Unable to proceed with installation

[DaveBryant]

For the past month or so I've been trying to update the Flash Player. I get to a certain point (about 90% through the installation) and I get an message: "Error: Unable to proceed with installation"

It opens the Flash support page in the browser and tells me my installion has failed. I've tried all of the suggestions, including doing a "clean install" by deleteing files in the Libray, as well as downloading and running the Flash player Uninstall app. So currently I have NO version of the Flash player installed and still get the erroe message.

Mac OSX 10.8.4

Mac Mini 2.26 Intel Core Duo - 8GB RAM

Browser: Firefox 22.0

Flash Player V 11.7.700.225 was trying to update to 11.8 -

Thanks in advance for any help you may provide.

Are you running any kind of antivirus? or firewall?

Have you tried installing under another user account?

[DaveBryant]

No antivirus or firewall. I just have one user account - but that's a good thought. When I get some extra time I'll set up a temporary user account and test from there ... thanks! I'll let you know what happens.

[DaveBryant]

Thanks Bob,

Your suggestion of trying the install under another user account worked. Why, I don't know ...

I only have one user account on my mac, so I logged in as a "Guest". Then opened each browser (Firefox & Safari) and installed the flash player for each. Once you log out as a Guest it says all you files and browser history will be deleted, but the install of the Flash Player stayed - for some reason.

best regards,

Dave

Repair permissions on your HD. That should prevent further occurrences of this.

[DaveBryant]

Yeah - I'm pretty anal about checking/repairing disk permissions. I think something else was stuck in it's craw but it's working now. Thanks again for the tip.
