I have this error under W98. PC has 128MB RAM. Is it not enough free RAM =8-? I have tested this in 3 differents PCs. The same application works fine under XP Home or Professional in a PC with 1GB RAM. I have tried a clean project with a simply button and, in OnClick event, a call to LoadLibrary('C:\TEST\ZIPDLL.DLL'). This API function returns 0 and GetLastError() 31. LoadLibrary('C:\TEST\UnzDll.dll') returns a non-zero value, but GetLastError() returns 6. ZipDll.dll 1.73.3.0 loads Ok: LoadLibrary returns a non-zero value and GetLastError() returns always 0. Can I make more test to find why ZipDll.dll don't load?
