I purchased Adope Photoshop Extended and loaded onto my laptop. I recently had to unintall all programs and can't seem to get Photoshop back on my computer.

I tried the link you provided but it didn't really help my situation.

What is your operating system?  What exactly means "can't seem to get..."?  What exactly is your Photoshop version?

See this article how to obtain the install logs: http://helpx.adobe.com/creative-suite/kb/troubleshoot-install-logs-cs5-cs5.html

I have the exact same question.  I have the serial number too.  I called Adobe help line, and they had a "technician" go into my computer and I thought he was going to reinstall.  He just showed me why the computer runs slow and why it didn't reinstall, and then told me if I still wanted his help it would be $300-$400.  !!  i thought it was a help line.... how does that help?  I didn't pay that much for the program!!

I desperately need help with this!
