I tried to install Adobe Photoshop CS4 and Adobe Director 11.5 on my Windows 7 PC, but I got the error:
Adobe Anchor Service CS4
I had Adobe Flash Professional CS5 installed already, so maybe it had some influence on that?
But now everything that was installed by Adobe is deleted. (Except for Adobe Air, X reader, Shockwave Player & Flash Player).
I tried to use
AdobeCreativeSuiteCleanerTool but it didn't work.
