Bob,

I have Office 2003 on my PC and all 3 versions of OWC controls. Looks like there isn't one to one correspondence between them. Anyway, each OWC control has it's own CLSID so you can check for them in the registry. Here's a sample code for Chart control. I used WSH to read registry for simplicity. You can use your favorite method.

oShell = CreateObject("WScript.Shell")

lcOwcChart9  = "{0002E500-0000-0000-C000-000000000046}"
lcOwcChart10 = "{0002E546-0000-0000-C000-000000000046}"
lcOwcChart11 = "{0002E55D-0000-0000-C000-000000000046}"

lcChartVersions = ""

TRY
	oShell.RegRead("HKCR\CLSID\" + lcOwcChart9 + "\")
	lcChartVersions = lcChartVersions + ", 9"
CATCH	
ENDTRY		

TRY
	oShell.RegRead("HKCR\CLSID\" + lcOwcChart9 + "\")
	lcChartVersions = lcChartVersions + ", 10"
CATCH	
ENDTRY		

TRY
	oShell.RegRead("HKCR\CLSID\" + lcOwcChart9 + "\")
	lcChartVersions = lcChartVersions + ", 11"
CATCH	
ENDTRY		
? SUBSTR(lcChartVersions,3)
