u2lcom.dll is missing

Hello,

I use crystal reports 8.5 to print labels from third party app.

Now I'm in a middle of migration to CR XI process and I came to problem with 2D barcodes.

I use IDAutomation_DataMatrixWindowsFontEncoder and IDAutomation_CrystalUFL. On CR8.5 this works perfect. Now on CRXI I get below error when the print is fired by application:

datacom.crystaldecisions.reports.formulas.FormulaException$MissingUFL:u2lcom.dll that implements this function is missing.

I found this dll in below folders:

C:\Program Files\Business Objects\Crystal Reports 11.5

C:\Program Files\Business Objects\Common\3.5\bin

C:\WINDOWS\system32

server has Windows 2003 32 bit. Crystal version - 11.5.10.1263.

Please advise what could be the problem.
Thank you
