If there is conflict between TWAIN 1.X and TWAIN 2.0…

[Massay]

Now our application is using TWAIN2.0 for our scan functions. but in these days, I got a strange issue:

1. The issue is occured in Vista 64Bit OS.

2. If our application with TWAIN 2.0 is installed the OS, then TWAINDSM.dll is installed in C:WindwosSysWoW64, in the time, our application work fine without problem.

3. But when Photoshop is installed, TWAIN 1.X file (TWAIN32.dll ) is installed in C:WindwosSysWoW64 too, in the time, our applictaion can open datasource ,but the scan cannot start, during we tracing, it is found the DS message cannot be got by our application and driver hangup.

4. Now EPSOn driver is used to verify .I cannot confirm if the issue is from driver side or DSM side,

Hope I can get the help from your…Thank you very much.

twain32.dll should not be in the c:WindowsSysWoW64, it should only be in c:Windows
There was an issue with an older version of the TWAIN 2.0 DSM that could not handle this issue, but it has been resolved.

Make sure you are using the latest version of the TWAIN2 DSM.

Can you post a TWAIN2 DSM log file?
