Mike, In the Rttyrite section of the Writelog.ini file in the Windows folder you can enter or change the location of MMTTY as follows: [Rttyrite] : : MMTTY_LOCATION=C:\Program Files\MMTTY\ I've never had a problem with Writelog or MMTTY in the Program Files folder. This particular version is running in XP Home. 73, Don VE3XD
