I have tried the link, and it doesnt work. I would really like a 16 bit support guide for MS WinPE as there are so many old tools which i still use, and would be nice on a boot cd. If anyone has managed this successfully, please let us know! Using the previous posted link, I try to run a 16 bit app and I get something like: "not enough disk space to create temporary 16 bit subsystem". I have tried loads of apps, which definitely do not need write access to a HD so that is not the problem. Any Ideas???
