Thanks. I've version 5.03 (377) 32bit
I've adapted syntax and other ini files that may be need to renewed when installing updates. So installing a new version of PSPad is something that may cost a lot of time to me. I usually do it once in 5 years. In the developer forum I found a pspad504b527x64.zip file what seems to be a portable 64bit installation. Without Autohotkey.ini and most other of the syntax-files. What I need is an update from 32 bit to 64 bit version with system are not included. So I'm not sure how to do a proper replacement from my version with autohotkey.ini and other settings to the 64 bit version. What about the system integration of PSPad? -- <https://forum.pspad.com/read.php?2,74263,74272> PSPad freeware editor https://www.pspad.com
