C:/Windows/SysWOW64/drivers/gm.dls

and the two copies are identical.
If the 32-bit version is working andf the gm.dls file is present in C:/Windows/System32, try copying that file into the C:/Windows/SysWOW64 folder.



Thanks folks. I followed the directory and found the file gm.dls is named as gm.dls.old. I changed it back to gm.dls and now everything backs to normal. No idea why my gm.dls file was changted to dm.dls.old. doesn't matter matter. BIAB works again!
