@andrecool-68 i have found some batch shortcuts don’t work in windows reg bat files for about 2 yrs now, like %~dp0 or %1, since path needs dbl \, u can replace w other environment vars or hard code path to npp since it shouldn’t change, that might do the trick. best to open regedit and edit paths there, then export key to reg file, then use npp to copy and add dbl \ that to your reg bat lines. i sometimes make a portable user-sys env var to use on that mach.
