I recently converted my system from SuSE 10.1 to OpenSuSE 10.2. When I upgraded VMware to v5.5.2, I was no longer able to change which ISO file I was using for Knoppix (that's how I discovered it at any rate). Turns out the issue was a little larger than that as something broke the virtual file system (VFS). From the VMware web site ( http://www.vmware.com/community/thread.jspa?messageID=545298) noticed that other people were having the same issue.
The actual error was The Folder could not be displayed - VFS error: Invalid parameters. Further on, a found a reference that fixed it for me. By loggng on as root, and executing the following statements:
cd /usr/lib/vmware/lib mv libpng12.so.0 libpng12.so.0.old ln -sf /usr/lib/libpng12.so.0 mv libgcc_s.so.1 libgcc_s.so.1.old ln -sf /lib/libgcc_s.so.1
I was able to get VMware working again. This is specifically for VMware Workstation 5.5.2 on OpenSuSE 10.2.
