- Scenario
- Launching Adobe Acrobat 2015 after purchasing a permanent license or subscription.
- Observed behavior

Clear Adobe Licensing Cache and Reset Activation Files
This solution clears out corrupted local license data and forces Acrobat to fetch fresh activation details from the server.
Corrupted licensing files such as SLStore, SLCache, and OPM.db are the most common culprits when a purchased Adobe product suddenly reverts to trial mode. Renaming these folders forces the software to rebuild fresh, error-free activation files.
Sign out of Adobe Acrobat. Open Task Manager (Ctrl+Shift+Esc) and end all Adobe-related processes, such as CoreSync, Adobe Desktop Service, Adobe IPC Broker, and AAM Updater.
Open Windows Explorer, navigate to C:\ProgramData\Adobe, right-click the 'SLStore' folder, and rename it to 'SLStore.old'.
Navigate to C:\Program Files (x86)\Common Files\Adobe, right-click the 'SLCache' folder, and rename it to 'SLCache.old'.
Navigate to C:\Users\[your username]\AppData\Local\Adobe\OOBE, right-click the 'OPM.db' file, and rename it to 'OPM.old'.
Restart your computer, launch Adobe Acrobat 2015, and sign in again with the Adobe ID associated with your purchase to verify the license.
Remove Conflicting Adobe Entries from the Hosts File
Incorrect entries in the Windows hosts file can block Acrobat from communicating with Adobe's activation servers.

Frequently Asked Questions
Why does my purchased Acrobat 2015 suddenly say it is a trial?
This usually happens when local activation files (like SLStore or SLCache) become corrupted, or if your connection to Adobe's activation servers is blocked. Resetting these files forces the software to re-verify your license against your Adobe ID.
Are there any compatibility issues with Adobe Acrobat 2015 on Windows 7?
Yes. Acrobat 2015 is an older, unsupported release, and Windows 7 has reached its official end of life. These factors can occasionally limit activation capabilities or cause compatibility errors during server communication.
Where can I find the AppData folder to rename the OPM.db file?
The AppData folder is hidden by default in Windows 7. To view it, open Windows Explorer, click 'Organize' at the top, select 'Folder and search options', go to the 'View' tab, and check 'Show hidden files, folders, and drives'. You can then navigate to C:\Users\[your username]\AppData\Local\Adobe\OOBE.
Do I need administrator privileges to fix this activation issue?
Yes, renaming system-level files in the ProgramData and Program Files directories, as well as editing the Windows hosts file, requires you to have administrator rights on your Windows 7 account.
