This is a 30-day demo copy of the Softools Z80/Z180 WinIDE program. After purchasing a license, you can enter the purchase code in the program itself and it becomes licensed and is a fully working program.

If you run the WinIDE and the WinIDE doesn't open and there is an entry for Softools WinIDE.exe in Task Manager. End all of them in Task Manager. Open Registry Editor. Click HKEY_USERS. Search for Open Multiple. It's 0. Change it to 1. The WinIDE will run.
There is something in Windows that is now causing the WinIDE already running check to lock up.
