Unable to execute the tool

Discussion created by iamlaksh3 on Aug 25, 2011

We have developed set of custom Geo processing tools and when we install these tools in Windows 2008 server tools are invalidated. All the tools and models shows red cross mark , on clicking "Unable to execute the tool" message is displayed.

Tools are developed using Windows 2008 R2 machine (64bit) and whereas these are deployed in Windows 2008 server. We are using ArcGIS 10 SP2.

Unable to find exact cause for tools invalidation, please help me on this
