Similar issue with Japanese Font
as explained by cdob:
Pcsview.exe resource --- object MainForm: TMainForm --- Font.Charset=SHIFTJIS_CHARSET solved
here with using
CODE
CopyOrExpand,"%SourceDir%\i386\c_932.nls","%TargetDir%\I386\system32"
hive_load,HKLM
reg_add,0x1,"%reg%\ControlSet001\Control\Nls\CodePage","932","c_932.nls"
hive_unload
after a long search
As in this pcsview.exe topic (post 2), i enabled my manuel script (Russian Font support disabled) and font working fine again

Maybe a similar solution can be found for this Russian case too ??
In addition to that, current script needs %systemdrive% writeable to install driver.
