.NET Forum / Visual Studio.NET / Setup / March 2005Problem with RemovePreviousVersions and GAC
Hello, I am developing installer project in Visual Studio 2003 for my components and I have a problem with upgrading assemblies in GAC. I need upgrading these assemblies with newer ones (AssemblyVersion is the same, but AssemblyFileVersion is different) and I wanted to do so with installer. I set up RemovePreviousVersions to True and increase installer Version, but after running this installer package on machine, old assemblies from GAC are deleted, newer ones aren'nt installed there. I must run installer package again, select Repair and after that I have installed newer assemblies. Is it a bug in Visual Studio installer package, or I am missing something? If it is a bug, does any workaround or any patch to VS or something else exist to solve this problem? Thanks, Zdenek D. Hello, Can you try to edit your msi with this tool http://www.microsoft.com/downloads/details.aspx?FamilyID=105dfc41-801e-4441-aa75 -7696d794f109&displaylang=en You need the tall called orca, and move the RemoveExistingProduct before Costinitialize in the InstallExecuteSequence table by changing the sequence numbers. It may help but the last time that I had a problem like this, the solution was this ;-) Cris > Hello, > I am developing installer project in Visual Studio 2003 for my components [quoted text clipped - 12 lines] > > Zdenek D. > Hello, > [quoted text clipped - 8 lines] > > Cris Hello, this trick helps solve my problem, thanks. ;-) Zdenek Something to watch out for with that solution is that you've taken RemoveExistingProducts out of the audited section of the install. So you can get a situation where you start the install, it removes the existing product, then starts installing the new product but you have a problem and it rolls back. It will not roll back the RemoveExistingProducts, so you are now left with neither old nor new products installed. Although it's true that a manually forced repair will install the assembly into the GAC, the automatic repair also does. If you actually run the app that uses that GAC assembly, it just repairs automatically - that's my experience of this.
