The file was really corrupted. After 13 hours I downloaded again from the same source - pmail.com and the filesize is the same as before. Thank you for your answers.

Today I downloaded file w32-463.exe and wanted to install the newest version of Pegasus mail for Windows.

Downloaded file size is 12 939 448 bytes and when try I try to install I get the message  "bad CRC 8973a0a8  (should be d72f1265)". Could you please hint me what am I doing not correctly? Thank you.

It seems you may have a corrupt file - where did you download it from?

Try downloading again from pmail.com and retry the install.  If you have any download accelerator or anti-virus which may be interferring with the download, you might have to turn them off.

Possibly a bad download.  Download again.   Download sites that I know of:

Community:  http://community.pmail.com/files/folders/pegcur/default.aspx

Pmail.com:  http://www.pmail.com/downloads_s3_t.htm.

If the CRC error happens on the new file temporarily disable any antivirus scanning then run again and see if that resolves it.
