Windows Vista and 7: A) Mol2Mol 5.6 runs without any problems under Windows 7 and Vista. Unfortunately, its Help system does not work because these OS versions do not support the older (but otherwise perfectly usable) WinHelp system by default. The solution:
You may want to download and install the recently upgraded and Vista compatible version of the WinHelp system. After this not only Mol2mol help but all other older Winhelp files will be functional again.
