PCPunch can't find WaspTimeServer on PC that doesn't have WaspTime client installed, and doesn't prompt to edit setting:

Cause: Registry entries for the WaspTimeServer service were not created in the Windows Registry by the installer.

Solution: Download and extract https://dl.waspbarcode.com/kb/wt/v7/WT7PCPunchRegistry.zip

Right click and Edit the .REG file to replace PutYourServerNameHere with the machine name of the PC where the WaspTimeServer service is running. Then double-click the file and allow Windows to add the information to the registry. Each logged-in Windows user on the PC who wants to run PCPunch will need to do this.
