I'm attempting to install the SP1 for Crystal Reports 2008. When I get to the actual installation phase after extracting all the files and agreeing to the T&C's i get the following message:
"Error 1500. Another installation is in progress. You must complete that installation before continuing with this one."
I've found a couple of references to this on the web and they all suggest deleting the InProgress Installer registry key. But, having done this and rebooted I still get the same message. Any one else seen this and know how to resolve it?
I'm using Windows XP SP3, I have CR9 and CR2008 already installed if that makes any difference.
I think (and perhaps someone can validate this) that the message I'm getting is because the same build already exists on my PC. As I said in my original post i'm trying to install SP1 which according to [https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/webcontent/uuid/90d7dc4e-36ce-2b10-d2b3-d5d72d067e21 [original link is broken] [original link is broken]|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/webcontent/uuid/90d7dc4e-36ce-2b10-d2b3-d5d72d067e21 [original link is broken] [original link is broken]] is build number 188.8.131.522. When I check my installed build number it is the same and so I must conclude that I downloaded and installed the V1 release. I guess what i'm saying is that it won't allow you to install the incremental SP1 on top of the V1 and it's error message is none to helpfull.
If anyone can confirm this then it may save others with this issue for wasting time as I have just done.
