PS CS5 Installation Error 20

[paulpegg-4RBW09]

I have tried several times to install PS CS5 in a win 7 system with 16GB RAM, intel i7 chip. I get the following screen each time. I disabled windows firewall and trojan hunter, have no other virus software. System has CS4 and lightroom Beta 3 installed. I also successfully installed this on my other system which is almost identical.

I installed AIR and ran it as admin and it found no problems.

Any thoughts?

Thanks,

Paul

I extracted the files to a network drive. I guess the installer did not like the remote path or win 7 denied access (more likely). i will copy the files to a local drive and try again.

Thanks for your prompt and accurate reply.
