Yes, i tried 'try...except' but still didn't solve.
</div>


<div>
That means the exception occurs nonetheless? Or what happens exactly?
</div>


<div>
After executing the 'InkCollector.Enabled := True;', all execution/codes after that won't be executed.<br />
Meaning it stops there.<br />
<br />
What i wanted is to check if Microsoft Tablet SDK is installed on the machine so that i won't load the InkCollector.

What you could do is to check against the registry if the software key occurs in the list of installed software products. I don't have the SDK here, but I checked for Java on my machine and it creates a registry key <br />
<br />
HKEY_CLASSES_ROOT\Installe<wbr />r\Products<wbr />\8A0F84233<wbr />1866D117AB<wbr />7000B0D610<wbr />002<br />
<br />
The Microsoft Tablet SDK should have its own key. You could probe if the registry key exists and if not, then the SDK is not installed. To find out the Tablet SDK key, you can search regedit using the string from the Add/Remove Programs control panel applet.<br />
<br />
The point is: if the SDK itself doesn't have an API to probe if its there, there is probably none. <br />
<br />
Concerning the exception matter: It is very strange that handling exceptions didn't work with your code. Are you entirely sure that you tried the code that I provided? Have you stepped through the code using the debugger? When exactly does the program halt and do you get any message?

<div>
Yes the 'try except' won't work in my part...sorry.<br />
And the checking of the registry, i think its not a good idea in my side.<br />
Thanks for the time.

Hi guys,<br />
<br />
What's the best way to check if the Microsoft Tablet SDK is installed in the machine? I encountered a 'Class not registered' error in my delphi program because the Microsoft Tablet SDK is not installed.<br />
<br />
delphi code that encounters error:<br />
InkCollector.hwnd := Panel1;<br />
InkCollector.Enabled := True; &nbsp; &nbsp; *** class not register ***<br />
<br />
Any idea guys?<br />
Thanks
