@Lin-Jeffer

can you reproduce this always? I’m running XP in a virtual machine and don’t have such problem.
Did you try to run npp without plugins used?

A BSOD happens when a Kernel-Mode failure occurs. Since no part of NPP runs in Kernel-Mode, it cannot trigger the BSOD directly. But AFAIR newer versions of Scintilla (a component used in NPP) use DirectDraw which in turn relies heavily on the graphics driver/card. So you may want to check for updates to your graphics driver or even try a different adapter (if possible).

Yes , I am using (no installer, bin_zip npp++) and no any plugin.
It always hang at second time launch.
Just launch npp++ , then exit. Launch npp++ again —> (hang)

It also happen on VM, XP clean install and npp++ only(virtualbox 4.2.36) ,
at second time launch, VM stop Siently(no any message or hint)
I put SciLexer.dll (from 6.9.2) into 6.8.7 , npp++ 6.8.7 run quite well , so I think it’s not the point .

I can start npp multiple times without any problem.
Did a test with >10 restarts.
Did you try running xp in safe mode?
What about using sfc tool, did you already run it?

@Claudia-Frank
In VM safe mode (no network),
Npp Launch first time , It silently stop. (same as normal mode)

Software compatible issue is case by case.
maybe MY CPU is AM1 (althon 5350) .
But an Editor normally don’t need too special instruction or I/O special function, heavy memory/search/move/display/fileIO.

Maybe npp change new compiler/or optimize deeply method . or link new library.

so older version is OK for me. I just report for someone as a hint.

I have the issue is that VS new compiler planed abandon XPSP2, not my AMDCPU .
I create a new XPSP3 VM in virtaulbox, then run NPP6.9.2 , it runs pretty well.

and I notice that VS2010 not support XPsp2, and NPP source code project file , had an M$ famous “X” , like docx, xlsx …
VcXproj.
