When Word/Excel is started it takes very long time (few minutes) to start. After that the toolbar works ok. Sometimes because of the long loading delay Word/Excel might display a prompt to disable the add-in.
On the PC running BarcodeMaker there are firewalls and antivirus software that restrict / enforce the access to the internet.
In this particular case, Word/Excel could not reach the revocation servers, which requires internet access to validate the digital certificate used to sign the BarcodeMaker add-in. The internet policies in place by the firewall and antivirus software caused this validation to be delayed which in turn cause Word/Excel to load very slow. Disabling certificate revocation was a workaround in this situation. Microsoft Office, uses settings from Internet Explorer Internet settings as outlined below.
1. Start Internet Explorer
2. Use Menu Tools->Options
3. Select the "Advanced tab"
In the Security section, uncheck the following check boxes:
-[ ] Check for publisher's certificate revocation
-[ ] Check for server certificate revocation
-[ ] Check for signatures on downloaded programs
These 3 checkboxes need to be unchecked.
4. Click Apply
5. Click OK and close Internet explorer
