You might want to try the 3.0.18 build Mike has announced.
On Win7 / Vista You should download and install the Microsoft VC runtime files from the link on the download page Mike has provided.
In Win7 / Vista you should disable the User Account Control < UAC > prior to adding the VC runtime files.
Then try to install the new version. If that fails you can try the procedure listed below.
My Win7 install went smoothly to CS4 32 bit.
To install 3.0.18 on my XP SP3 system...I had to follow the procedure listed below....
- un-install CM using the Add/Remove programs function of windows.
- Download and install the VC runtime files from Microsoft
- re-boot
- install CM 3.0.18
Any other combination caused a failure.
Please let us know if you have problems...
