[JIRA] [plugin] (JENKINS-7303) Could not find cygpath on Win64 machine
Neeme Praks commented on JENKINS-7303 Could not find cygpath on Win64 machine I added a comment under JENKINS-20364, but it is somewhat relevant also for this issue, so I'm copying parts of it here. I'm not sure the change made here actually fixes anything (did someone test this?). The "Wow6432Node" subkey seems to be implementation detail of Windows registry and the application code should not care about it. Instead, it should use the relevant access bit (as described above). Also, my tests have shown that with current code, 64bit JVM running on 64bit Windows can access "HKEY..WARE\Cygwin\setup". The problem is with 32bit JVM running on 64bit Windows: it looks up "HKEY..WARE\Cygwin\setup" but Windows translates that into "HKEY..WARE\Wow6432Node\Cygwin\setup" (which is missing). And, when it tries to access "HKEY..WARE\Wow6432Node\Cygwin\setup", Windows probably translates that into "HKEY..WARE\Wow6432Node\Wow6432Node\Cygwin\setup" which is also missing. So 32bit JVM running on 64bit Windows has no access to "HKEY..WARE\Cygwin\setup" unless it specifies the special KEY_WOW64_64KEY flag. I'm not sure if the other scenario of 64bit JVM running on 64bit Windows trying to look up "HKEY..WARE\Wow6432Node\Cygwin\setup" works or KEY_WOW64_32KEY flag should be used instead (covering the case when "HKEY..WARE\Cygwin\setup" is missing but "HKEY..WARE\Wow6432Node\Cygwin\setup" exists). Should probably test that.

Should probably test that. Assuming that the fix made here actually works (otherwise it would have been re-opened long ago), my second comment can be ignored 64bit JVM running on 64bit Windows looking up "HKEY..WARE\Wow6432Node\Cygwin\setup" probably works. The problem is that this fix does not work for 32bit JVM running on 64bit Windows (see my comment on JENKINS-20364 for details).

Neeme Praks reopened JENKINS-7303 Could not find cygpath on Win64 machine Reopening as the solution does not work for 32bit JVM running on 64bit Windows. I'm not sure if this should be solved here or under JENKINS-20364. Feel free to resolve if JENKINS-20364 seems more appropriate.
