We are using Quest Geo Solution’s Grid InQuest DLL (GIQ60.DLL) within an SQL Server Integration Services (SSIS) package. We have managed to use this without problems locally (32bit) by using tlbimp to create a .NET wrapper (interop). However, when this moved to our integration server this does not work as the server is 64bit.
The GIQ60.DLL is a 16bit DLL and the vendor has confirmed that they no longer actively support this. If we run the 32bit version of DTEXEC on the server , the package runs without problems. Is there a trick/way to convert the .NET wrapper to enable this to work SQL Server Integration Services (64bit install).
Alternatively , we need a replacement free 32bit .net library that will convert OS grid (Easting /Northings) into geospatial longitude/latitude for both UK and Ireland (they use different grid systems) then that would be a viable solution.
The only other solution i can think of is to create a windows service (32bit) that hosts your component and exposes it as WCF or Remoting end point. Then use script task in SSIS to access it. This way you can run your package in 64bit DTEXEC and your component in 32bit process.
