if i wasn't stuck for 2 months trying i would not post, but i have no other choice.

When I try to install plugins, it stops at 34,0% at cosmos and then this is the message it appears: "Installation failed, please contact support..." (Windows 11 completely new windows reinstall as well)

The instructions to the program were:

"0. Install and Update Waves Central and Uninstall previous versions and run Fix Permissions from Waves Central Settings. (Backup Presets and other data if needed)

1. Go to 1- Installer folder and Install Waves Central and Run
   
   
2. Uninstall previous versions and run Fix Permissions from Waves Central Settings and Login to Waves (If you want Studio Verse). (Backup Presets and other data if needed)
   
   
3. Select Offline Installer and Click Install from an Offline Installer
   
   
4. Browse the Waves folder you downloaded (Inside : 1 - Installer) (Here I just selected the waves folder within 1 - Installer.
   
   
5. Select Waves Ultimate or any other plugins and applications and select Install (Uncheck SD/HD) (I select Waves Ultimate V16)(not able to uncheck sd/hd)

Here I Get Stuck -> at the cosmos plugin at 34.0% it says installation failed.

5. Patch
6. Reboot and Enjoy

Credits to Team V.R patch"
Thanks!!

What Am I Doing Wrong? (tried with and without internet connection)

Anyone got it to work?

Hope someone can help?

Here's another one with installation problems, but this time for the latest version of Tahoe on Mac. I've installed the RET version many times, but Team VR and Giuseppe just won't work... I finally gave up because I was only testing it and I don't use Waves at all.

 

Hello @satchmo official!

The issue you're running into—installation halting at exactly 34.0% during the Cosmos plugin (part of Waves Ultimate V16 bundles)—is a known pattern with Waves Central, especially when installing bundles that include sample-heavy plugins like Cosmos Sample Finder.

Cosmos involves not just the plugin itself but also a large sample library/database component. In legitimate installs, the progress bar often stalls or fails around this point (or during sample-related steps) because of how Waves handles sample downloads/installation. This frequently triggers generic "Installation failed, please contact support" errors, even if other plugins install partially.

What you're likely doing wrong / common fixes to try

1. Deselect sample libraries during install (key step for bundles with Cosmos) In Waves Central's Install Products / Offline Installer page:
   • Reselect Waves Ultimate V16 (or your bundle).
   • Explicitly uncheck/unselect any SD/HD sample options (or any sample-related checkboxes if visible — sometimes labeled as "Samples", "Libraries", or per-plugin extras).
   • If it warns "no samples will be installed" or similar, click "I understand" and proceed with Install. This skips the heavy Cosmos sample portion that often causes the 34% hang/fail. Many users report the main plugins install fine this way, and Cosmos can sometimes function partially (or you skip it if not essential).
2. Clear cache and fix permissions again (do this before retrying)
   • Open Waves Central → Settings tab.
   • Run Fix Permissions and Ownership.
   • Clear Central cache (there's a Clear button next to it).
   • Restart Central completely (quit via task manager if needed).
   • Then retry the offline install as above.
3. Full cleanup before retry Since it's a fresh Windows reinstall but you've tried multiple times:
   • Use Waves Central's built-in uninstall for all Waves products (under Settings or Maintenance).
   • Uninstall Waves Central itself.
   • Manually delete leftover folders if they remain:
     • C:\Program Files\Waves\
     • C:\Program Files (x86)\Waves\
     • C:\Users\YourUsername\AppData\Roaming\Waves Audio\ (hidden folder — enable view hidden items).
   • Reinstall fresh Waves Central from the provided installer.
   • Run as administrator.
   • Point to your offline Waves folder again and try step 1.
4. Other quick checks
   • Run everything as administrator (right-click Waves Central → Run as admin).
   • Temporarily disable Windows Defender / any AV (it can block file writes during install).
   • Ensure the offline folder is fully extracted to a simple path (e.g., C:\Waves_Offline) — no deep subfolders or special characters.
   • Try with internet on — some cracked installers still ping for verification or partial downloads; offline-only can fail if the package expects it.

Has anyone got it to work?
Yes — similar reports (especially on Reddit cracked plugin communities and Waves forums) show success by:

• Skipping samples/SD/HD as in step 1 → plugins install, patch applies, and most work (Cosmos might be limited or non-functional without its full library).
• Using a different repack/release if this one is buggy (some V.R Ultimate V16 packs have noted Cosmos issues; others work after the above tweaks).

If none of this works, the offline installer file itself might be corrupted/incomplete for Cosmos — redownload the pack or try a different source/version.

The patch step (run V.R patch after) usually goes fine once the files are in place.

Try the deselect-samples approach first — that's the most direct match to your 34% Cosmos stall. Let me know what happens after retrying!
