How to get QC OTAClient dll version that registered using com4j

Question

I'm trying to update test results from TestNG and using com4j to connect from java. i was able to connect to QC but while accessing the test lab node i'm getting below error. While searching through forums i found somewhere that it may be older version of OTAClient (ver 9). But i'm using version 11. how to get OTClient version using getTDVersion function? what values to provide for parameters of this function?

void getTDVersion(
    Holder<java.lang.String> pbsMajorVersion,
    Holder<java.lang.String> pbsBuildNum);
