On the target computer there isn't installed VS but framework of course is (the same version as on my personal computer) I googled something and I installed something called: Office 2007 Primary Interop Assemblies becouse I thought that It could resolve the problem but unfortunatelly application still crush:(. Please help:(.

This operation failed becouse the QueryInterface call on the COM component for the interface with IID: 000634034-0000-0000-C000-000000000046 failed due to the following error: No such interface supported >.
