PRINT SHOP IS NOW TOTALLY UNPROTECTED for floppy disks, USE DOS'S
|
||
DISKCOPY OR COPY COMMAND TO MAKE A BACKUP.
|
||
|
||
For hard disk users, the 'location' of the PS.EXE program is
|
||
recorded in the 1st two bytes of the MAINPIC.DAT file.
|
||
When the 'printshop install' is performed to hard disk,
|
||
the location of the PS.EXE is recorded in the MAINPIC.DAT...
|
||
You can use Norton's utilities to look at the dirctory entry
|
||
for the PS.EXE file, and write down the FAT which is the 26-27 bytes
|
||
or last 2 bytes of the 4th entry past the file extention name.
|
||
Then transcribe these 2 bytes into the 1st two bytes of the MAINPIC
|
||
file, and write it back to disk... PRINTSHOP will now work from
|
||
the hard disk. BEWARE - if you copy, restore, or move the PS.EXE
|
||
file, you must re-do these procedures because the entry will change,
|
||
and no longer match the entry in the MAINPIC.
