If the program was as bad as you say, then NOBODY would be able to even launch it -- which is clearly not the case.
There are so many possible issues, many related to your system specs, including an out of date video card driver, out of date Quicktime version, etc.
But the fact that the same download isn't working on two different computers seems to indicate the problem is with your download.
You did unzip your file before you tried to install it, didn't you? (Some people try to install it from within the Zip file.)
Did you use the same download on both machines or have you tried to download again? It could possibly be that you got a buggy download. Many people have found success downloading a second time.
You may also want to contact Adobe tech support. You may well have issues on your systems that are too deep to troubleshoot on this forum.
Yes, there can be issues with this program --especially on Windows 7 64-bit. But if you can't even open the program, you've got something going on that's much deeper than a buggy program.
- Install all Windows updates
- Install latest version of QuickTime (v7.6.6 at time of writing)
- Install most recent graphics and sound drivers from the manufacturers web sites
- Run Disk Cleanup
- Run Defragmenter
- Post back here with the necessary information described here: Got a Problem? How to Get Started
- Disable realtime protection from anti-virus / anti-spyware products (if we can get PRE working for you these can be added back one-at-a-time to see if they contribute to your difficulties).
Insanity is hereditary, you get it from your children
From bad to worse!!!
I did as suggested and again all seemed well untill I tried to use the
program which now says my trial period has expired. As I only tried a couple
of days ago this seems very odd.
For reference the Virt mem avaiable is 11260 MB ans I do have the latest
quick time etc.
