.BTM association doesn't work anymore

Nov 23, 2011
Hi everybody,

with no reason the .btm extension refuse to be executed by tcc.exe. I want to use a batchfile named digall.btm. I used it the last two years without any problems. Take a look at this:

[C:\Program Files\JPSoft\TCMD13x64]dir digall.btm

Datenträger in Laufwerk C ist unbezeichnet Seriennummer ist 3ae1:dd3f
Verzeichnis von C:\Program Files\JPSoft\TCMD13x64\digall.btm

16.04.2015 14:52 117 digall.btm
117 Bytes in 1 Datei und 0 Verzeichnisse 4.096 Bytes belegt Bytes frei

[C:\Program Files\JPSoft\TCMD13x64]digall
TCC: Unbekannter Befehl "digall"

[C:\Program Files\JPSoft\TCMD13x64]assoc .btm

[C:\Program Files\JPSoft\TCMD13x64]ftype btm_auto_file
btm_auto_file="C:\Program Files\JPSoft\TCMD13x64\tcc.exe" "%1"

[C:\Program Files\JPSoft\TCMD13x64]ver /R

TCC 13.04.63 x64 Windows 7 [Version 6.1.7601]
TCC Build 63 Windows 7 Build 7601 Service Pack 1

For those unfamiliar with german, Unbekannter Befehl "digall" means unknown command "digall".
I looked through the following registry hives:
an everythings looks good.
Unnecessary to mention that once I add the btm extension to the filename like "digall.btm", it magically works as expected.

Any Idea?
