Retail POS installation issue

Hi,

I am unable to install retail components while doing AX installation. Initially I didn;t have Sync Framework installed, so i clicked on the link and installed it. but when i try to revalidate, it still shows the same error. I have tried it a number of times and it all failed to get thru…I even restarted my system to get past it but without success.

Any idea what am i missing here?

Thanks,

Raju
