INI File problem

Sorry, my English is very very bad.

This one is ok.

ClearErrors

ReadINIStr $R2 "some.ini" "SomeSection" "SomeKey"

  IfErrors +3

   DeleteINIStr "some.ini" "SomeSection" "SomeKey"

   WriteINIStr "some.ini" "SomeSection" ";Somekey" "$R2"

This one is not ok right now. It never got value from ";SomeKey", I remembered old NSIS 2.0 do this code ok.

ClearErrors

ReadINIStr $R2 "some.ini" "SomeSection" ";SomeKey"

  IfErrors +3

   DeleteINIStr "some.ini" "SomeSection" ";SomeKey"

   WriteINIStr "some.ini" "SomeSection" "Somekey" "$R2"

Is this a bug or something?

I always used those way to temporary remark some line inside inifile successful, and now NSIS 2.12 can not do the second code.

maybe problems with comments handling?
as you may know, ';' is the beginning of a comment in NSIS.
there have been some fixes to the comment handling in latest NSIS versions, that may cause such problems..

Rather than a bug that has been introduced, it sounds like a bug that's been fixed. Semicolons indicate a comment in an INI file, so it would make sense that ReadINIStr $R2 "some.ini" "SomeSection" ";SomeKey" doesn't work. In fact, a quick test with GetPrivateProfileStringA() confirms that trying to read the value of ";SomeKey" does not return a (useable) value.

ah, yes, i thought it may have been something on compiletime, but you're right, it has to do with ini file format.
