License or sign-in error
If the app says "trial," "unlicensed," or asks for sign-in repeatedly, start here.

App crashed or will not open
If a desktop app on your work computer fails to launch, hangs on a splash screen, or closes seconds after opening, work through these checks before reinstalling. Most app-crash incidents are about pending updates, the wrong account being signed in, an add-in or a single bad file rather than the application itself being broken.
Step One
Confirm what is actually happening
Note exactly what you see
Does the icon do nothing? Does a splash screen appear and disappear? Does the app open and then close? Does an error window appear with a code? Each of these has a different fix.
Check whether the issue started after a recent change
A Windows update, an app update, a password change, a new computer, or a new add-in are the most common triggers. If you can name a change, mention it when you contact support.
Test whether other apps are affected
If only one app fails and everything else is fine, the problem is that app or one of its files. If multiple apps from the same vendor (for example all Autodesk apps, or all Microsoft 365 apps) fail at once, the problem is shared and is usually account, license, or update related.
Step Two
Try these stable fixes first
Restart the computer once
This is not a joke. Many app launch failures clear after a restart because a pending Windows update, a stuck driver, or a locked file finally finishes or releases. Save your work, restart the computer, then try the app again.
Install pending updates for the app and Windows
Open the vendor's updater (Autodesk Access, Creative Cloud, Microsoft Store, etc.) or Windows Update and let any pending updates install. App startup failures often resolve themselves after a held-back patch finishes.
Sign in to the work account first
If the app uses a sign-in (Microsoft 365, Autodesk, Bluebeam, Adobe, Bentley), open another app from the same vendor and confirm the correct work account is signed in. A wrong-account state can prevent another app from launching cleanly.
Try opening the app without a specific file
Do not double-click your file. Open the app from the Start menu first. If the app opens by itself but crashes the moment a specific file loads, the file is likely the cause, not the app. Test a smaller known-good file.
Try safe mode or no-add-ins mode if available
Microsoft Office apps support holding Ctrl while launching to start in safe mode. Bluebeam, Adobe, and Autodesk products have similar add-in disable options. If the app opens cleanly without add-ins, an add-in is the cause.
Slow Down
Do not do this yet
Do not uninstall the app yet
Uninstalling sometimes loses settings, profiles, signatures, plot styles, or templates that take a long time to rebuild. Reinstall is a last resort, not a first step.
Do not run system-cleanup tools or "PC optimizer" tools
These rarely fix real problems and often break other things. Stick to the vendor's supported repair tool (Office Quick Repair, Adobe Cleaner, Autodesk Access repair, Bluebeam repair, QuickBooks Tool Hub).
Do not delete the app's local folder by hand
If a file inside %localappdata% or %appdata% is the problem, the vendor's support tool or IT will know what is safe to remove. Deleting the wrong folder can erase signatures, autocorrect data, profiles, or shared content.
If You Need IT
What to send support
The exact app name and version
"AutoCAD 2026," "Bluebeam Revu 21," "Outlook (Microsoft 365 Apps)" - not just "my CAD program." Versions are usually under Help > About or File > Account.
A screenshot of the error or last screen shown
If a window pops up with an error code or message, take a screenshot before clicking OK. If nothing visible appears, take a screenshot of the desktop showing that no window appeared.
What changed and when the issue started
"Worked yesterday, broke this morning after Windows updated overnight." "Worked on my old computer, has not worked since the new laptop." Timing is half the diagnosis.
Whether other apps from the same vendor work
If all Autodesk apps fail but Microsoft apps work, IT can focus on Autodesk sign-in or licensing. If everything fails, it is usually Windows or account level.
CAD / AEC Notes
Extra checks for design apps
Check the vendor helper app
Autodesk Access, Bentley CONNECTION Client, Adobe Creative Cloud, Bluebeam sign-in, and Esri licensing all affect whether the main app launches. If the helper app is signed out or stuck, fix that before reinstalling the design app.
Separate startup crashes from file crashes
Open Revit, AutoCAD, Civil 3D, MicroStation, ArcGIS Pro, or Bluebeam without opening the project file. If the blank app opens but one model, drawing, or PDF crashes it, collect the file path and test a known-good file.
Watch for graphics and add-in clues
Crashes during splash screens, 3D view loading, PDF rendering, or ribbon loading often point to graphics drivers, add-ins, plug-ins, or workspace profiles. Include the exact moment of failure in the ticket.
