Struggled with this one for 2 days and went through tons of
forums till I found this one:

SokSa.Icy had the right idea.

My particular problem also involved going through the
registry to remove all instances of Visual Studio 2008 as
well as a .Net 3.5 hotfix that I could not get rid of.

Once I uninstalled and did everything this guy did, I also
went through the registry and searched/deleted all
instances of the framework hotfix to get it out of the
add / remove dialog box in control panel.

I also used wise registry cleaner to make sure I got all
inconsistencies out of the way, rebooted, and
installed .net 2.0 Express.

After a successful installation, I rebooted again and ran
sql server 2005 express installation and presto - back in
business...

God Bless the user forums on the Net - Microsoft would have
made a bundle off us by now in tech support fees...

Hi, I am trying to encode data from flatfile and then to decode the encoded data to original form. Procedures that I followed:- 1. Encoded the field 'A_ID' using AES_ENCRYPT(A_ID,'abd') in the expression transformation. The A_ID got encoded in the output table(oracle) 2. To decode this back I used AES_DECRYPT(A_ID,'abd'). But after executing the workflow, I am not getting any data in output. can anybody tell me how to decrypt the encoded data back to original form ??
