Files\Camera Assistant Software for Toshiba\driver\32bit\”.

In firsts line you have this:

Version

Provider=%cec%
CatalogFile=casflr.cat
DriverVer=04/24/2007,6.2.208.0424
;LayoutFile=layout.inf

of the line) that contain “ClassGUID”:

ClassGUID={6bdd1fc6-810f-11d0-bec7-08002be2092f}

Now put a new line after the older line with the correct class ID
found in the register

After modified .INF file completely it should be show like below:
