Upgrade from 4 to 5 stalls

When "Running package scripts" during installation of Parallels 5 on my Macbook Pro (Snow Leopard), the installation process stalls near the end with "About a minute" remaining, crawls for an hour or so, and finally hangs just short of completion. Happens every time I try to install the downloaded installer package.

For no particular reason I tried to upgrade 4.0.3844 to build 3846, and that doesn't work either. I aborts immediately after I click to "run a program to determine if the software can be installed."

Any insight as to what may be underlying these reactio

 

Hello,

Could you please send the screen shot of the error screen that you receive.

 

I did not receive an error message. The install bar just kept running, but after several hours it was apparent that it was not going to finish the install. I had to end the install by cmd-opt-esc. I did try again, with the same result.

Subsequently, using the same download of Parallels 5, I tried to upgrade from 4 to 5 on my wife's Imac running Leopard. The install did not hang, but when I finished and restarted it was still running Parallels 4. I updated that with a download of build 3846. That was successful.

 

Hello,

Please try to uninstall Parallels using the latest PD 5 link and install it again.

 

I was able to uninstall PD using the Parallels 4 installer disk. Then I attempted to install Parallels 5 from the downloaded installer, and it hung again. The problem was identical to my previous attempts as described in my first post.
