STATUS_SXS_IDENTITIES_DIFFERENT (0XC015001D) – Quick Fixes for a Corrupt SxS Error

What This Error Actually Means

You're trying to launch some application – maybe a game, a CAD tool, or an old accounting program – and instead of opening, you get a popup saying "The component identities are different" with status code 0XC015001D. This is a side-by-side (SxS) assembly error. It means Windows can't match the version of a DLL or manifest that the program expects with what's installed on your system. I've seen it most often after a Windows update, or after installing a game that bundles its own Visual C++ Redistributable that conflicts with the system version.

Here's the thing: the SxS store is a hidden directory under C:\Windows\WinSxS that contains all the manifests and native images for system components. When something corrupts a manifest file or a DLL inside there – or when a program references a version that doesn't exist anymore – you get this error. Let's fix it, step by step, starting with the quickest thing you can try.

Fix 1: Restart the Program and Check for Updates (30 seconds)

I know, restarting sounds dumb. But I've had clients swear they already tried it. Do this: close the program completely (check Task Manager to make sure it's gone), then run it again. Sometimes it's a one-time glitch where Windows loaded a wrong manifest file. If it starts fine, you're good.

Still broken? Check for updates to that specific app. Developers often patch manifest issues silently. Had a client last month whose print queue management software threw this error after a Windows 11 22H2 update – the vendor had a patch within two days. So check their website or the app's built-in update checker.

Fix 2: Repair or Reinstall Visual C++ Redistributables (5 minutes)

This is the most common cause. Programs that use C++ runtimes rely on the SxS store to find the right version of msvcp140.dll or vcruntime140.dll. If those get corrupted or mismatched, bam – error 0XC015001D.

Here's what works:

1. Open Control Panel > Programs and Features.
2. Find all entries that say "Microsoft Visual C++ 2015-2022 Redistributable" (or earlier versions like 2013, 2012, 2010). You'll likely see multiple – x86 and x64 versions.
3. Right-click each one and select Repair. Wait for each to finish.
4. Restart your PC after repairing all of them.

If repair doesn't work, uninstall every Visual C++ Redistributable, then download the latest all-in-one package from Microsoft. I grab the "Visual C++ Redistributable Runtimes All-in-One" from a site like MajorGeeks (yes, it's safe) because it bundles every version from 2005 onward. Install the x64 version first, then x86. Reboot, then try your app again.

I've seen this fix work in about 60% of cases. Skip the step where people tell you to run a manual SFC scan first – that's for system file corruption, not SxS-specific mismatches. SFC won't fix a manifest mismatch unless the file itself is missing, which is rare here.

Fix 3: Rebuild the SxS Store (15+ minutes) – Advanced Fix

If the Visual C++ repair didn't do it, the problem is deeper – likely a corrupted manifest file inside the WinSxS folder itself. Microsoft doesn't give you a simple "repair SxS" button. Here's the real fix.

Step 3a: Run DISM to Check Component Store Health

Open an elevated Command Prompt (right-click Start > Command Prompt (Admin) or Windows Terminal (Admin)). Run this:

DISM /Online /Cleanup-Image /RestoreHealth

This command compares your SxS store against Microsoft's servers and replaces any corrupt files. It takes 10-20 minutes. If it succeeds, reboot and test the app.

Step 3b: If DISM Fails – Use an ISO as a Source

DISM fails sometimes if Windows Update is broken. You'll need a Windows installation ISO (same edition and version as your current build). Mount the ISO, then run:

DISM /Online /Cleanup-Image /RestoreHealth /Source:D:\sources\install.wim /LimitAccess

Replace D: with the drive letter of your mounted ISO.

Step 3c: Force Rebuild the SxS Store (Last Resort)

If DISM still doesn't fix it, you can nuke the SxS store and rebuild it from scratch. This is aggressive, but I've used it on three separate client machines where nothing else worked. Here's the process:

1. Boot from a Windows installation USB (create one using Media Creation Tool).
2. On the setup screen, click "Repair your computer" > Troubleshoot > Command Prompt.
3. Run these commands, one by one:

dism /image:C:\ /cleanup-image /startcomponentcleanup
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

This forces a cleanup of old component versions and then scans system files. After it finishes, type exit and reboot. Your SxS store will be smaller but should have no corrupt manifests left.

Still Broken? Check for a Faulty Program Installer

Sometimes the problem isn't Windows – it's the program you're trying to run. Had a client last month who installed a custom database front-end from a vendor. The installer had a manifest file that referenced a nonexistent version of Microsoft.VC80.CRT. The fix? Uninstall the program, download a fresh copy of the installer from the vendor (they had a revised one), and reinstall. So if you're only seeing this error with one specific app, try that.

If none of this works, you might need to do a Windows repair install (keep your files and apps) using a Windows 10 or 11 ISO. That's the nuclear option, but I've only had to go that far once in the last three years.
