(I've tried changing of properties for decompress.exe only)
I've registered *.ocx-file by using cmd and pasting there commands:
regsvr32 /u Comdlg32.ocx regsvr32 /i Comdlg32.ocx
which were copied from site, recommended by You in above post.
After that, compress.exe works also, but both programs - after system's prompt.
