Information regarding the integration feature
If you have User Account Control (UAC) activated you have to run AS-CRC32 as Administrator in order to add/update or remove the integration feature. This can be done by right-clicking on the EXE file. (Note: When you make a larger Windows upgrade, this integration may be cleared, then you need to add it again.)
