11.5 is 5+ years old and 12.10 is one year old. If your IT department wants you to be on the current Toad version that would be 12.12 released one week ago. I don’t know what it means to purchase from your company app store, but if they route the PO through Quest or another vendor then you should be able to get 12.12. Perhaps they can credit your 12.10 purchase towards the current version?? You’ll want to contact Quest Sales or the vendor from which it was purchased.
