I am working in ProjectWise, but when I tried this outside of ProjectWise, I received the same error message.
I only mention this because the filename listed in this image is a dead giveaway to this being a file in ProjectWise, and I don't want anyone to follow that path. ProjectWise is a red herring in this problem and can be ignored. Note that I also learned a while ago, that for this to work in ProjectWise, you need to check out the xls file along with the csv file.
However, I recently had the 64 bit Office 365 on my PC and even after reinstalling ProjectWise, the office Integration is not working 100% as it used to. Likewise, outside of ProjectWise, even Windows is having issues recognizing that I now have 64 bit Office and not 32 bit Office.
I suspect that this issue is related to that problem.
Before this upgrade, this process worked just fine.
Is these someplace in the registry that I can fix this so that the remap tool recognizes my 64 bit Excel is an acceptable application for the remap tool. Without this, I am down to manually editing a remap csv file and this is far from ideal.
