LeadTolls 12 not showing graphics

I am attempting to install an older VB6 app on a new Win7-32bit computer. The VB app uses LeadTools 12 for displaying graphics files. Unfortunately the graphics do not display. The program and data are housed on a Active Directory Server. Several drives are mapped to it.

I did not do an install. What I did was copy the following files to the \windows\system32 folder:

ltdlg12n.ocx, ltocx12n.ocx, ltdlg12n.dll, ltkrn12n.dll, ltdis12n.dll, ltefx12n.dll, ltfil12n.dll, ltimg12n.dll, lttwn12n.dll

comdlg32.ocx, mscomct2.ocx, mscomctl.ocx, richtx32.ocx, tabctl32.ocx,

then I used regsvr32 to register the 7 .ocx files.

I create a shortcut to the app on the server and launch it. I get no error messages (like missing ocx or dll) but no graphics (.png or .jpg) appear. All other aspects of the app work.

I am at a loss. Any suggestions would be most appreciated.

Paul,
Are you the developer who owns LEADTOOLS and originally built or compiled the application? If yes, please refer to the help topic "Files to be Included with Your Application" because other files are needed to load images.

If you still need help, send your toolkit serial number to support@leadtools.com (do NOT post it here) and provide more details about the lines of code that fail and the error numbers they return.

To close this out for anyone interested...

I was missing the LeadTools filter (codex) files needed. lfpng12n.dll (for PNGs), and lfcmp12n.dll (for JPGs). Once they were added to \windows\system32 the graphics started displaying properly.

I guess because they started with LF instead of LT I just missed them.
