I inadvertently uploaded a zip for ReRun that included an extra exe file. I have corrected that on the site. The current version is 188.8.131.52.
I think the first change I will make will be to create a quick and dirty semi-installer just to copy the 32 bit or 64 bit embedded code to the file ReRun.exe in the current folder, depending on the "bitness" of the user's OS. Just so the user doesn't have to do it by hand.
So instead of the 2 exes the next upload will likely have one file ReRunSetup.exe or something similar. It will likely just use the AHK install command. That should be the simplest way.
Edit: Now the zip file includes a Readme.txt and one exe as described. Just run ReRunSetup.exe in an empty folder. It will copy either the 32 bit or 64 bit version of ReRun to ReRun.exe in that folder. Note that it is set to not overwrite existing files. To update a folder where ReRun.exe already lives, make sure you have quit ReRun.exe from the tray if running, then delete it, before running ReRunSetup.
Note that the Donate and Visit Hotkey Page commands now work, even if they are a bit slow to react. The check for updates I may just remove as the maintenance is klunky.
