This is caused by either:
The user not having full read/write permissions to the Service Manager library file.
The library file being set to read-only.
Note: You may not have the permissions to do the below, so we recommend that you speak with your IT for this.
To check library file permissions:
Navigate to C:\Program Files (x86)\Access Applications\Service Manager.
Right click on the file SME.lbr.
Select Properties.
Click on the Security tab.
Click Edit.
Now either modify the user's permissions (Or a security group the user is in) to have Full Control of the file, or add the user then give them full control.
To add a user, click Add, search for them and then select Full Control and then click OK.
Click OK to apply the changes.
The above may also need to be applied to another location, Check the following location for another SME.lbr file:
C:\Users\<affected user>\AppData\Local\VirtualStore\Program Files (x86)\Access Applications\Service Manager.
Replace <affected user> with the username of the user not able to log in.
Follow the above steps again to check user permissions.
If the above has been completed, and the user is still unable to log in, then it may be because the .lbr file is marked as read-only.
To check and resolve that, follow the below:
Navigate to C:\Program Files (x86)\Access Applications\Service Manager.
Right click on the file SME.lbr.
Select Properties.
Untick Read Only.
Click OK to save the changes.
Once again, the above may need to be done in another location.
Check the folder C:\Users\<affected user>\AppData\Local\VirtualStore\Program Files (x86)\Access for another SME.lbr, and run through the above steps again.
If all of the above fails, then you can delete the SME.lbr file in the
C:\Users\<affected user>\AppData\Local\VirtualStore\Program Files (x86)\Access
folder, and run Service Manager again. This will recreate the file and resolve the issue.
With these check all complete, you should now get a login box to log into Service Manager
