Remove Tool Advanced (UltraCafModels) installation fails with Exit Code 127 — installer cannot allocate 1GB+ memory buffer
System:
- Device: ASUS ROG Zephyrus Duo 15 SE (GX551QS)
- CPU: AMD Ryzen 9 5900HX
- RAM: 32GB (12GB+ free during installation)
- OS: Windows 11 Home x64 (Build 26200)
- Photoshop Beta version: 27.7.0.3511
- Adobe installer process: 32-bit
Steps to reproduce:
- Open Creative Cloud Desktop
- Navigate to Photoshop Beta → Get Add-ons → Remove tools advanced components
- Installation reaches ~49-62% and fails with Exit Code 127
- Error repeats identically on every attempt regardless of system state
What was tried without success:
- Multiple clean installs of Photoshop Beta and Creative Cloud using Adobe CC Cleaner Tool
- Cleared C:\adobeTemp before each attempt
- Ran Creative Cloud as Administrator
- Increased Windows Virtual Memory (page file) manually
- Set full permissions on all Adobe temp folders
- Disabled all background Adobe processes before installation
- Attempted installation from both Photoshop Beta and standard Photoshop
- An Adobe remote support agent accessed the system and modified AppData folder permissions without resolving the issue
Possible root cause identified from logs: The Adobe installer runs as a 32-bit process. A 32-bit process has a maximum virtual address space of 2GB. After Windows reserves space for kernel, DLLs, and heap, there is no contiguous block of ~1.07GB available — regardless of how much physical RAM is free. This is a design issue in the installer: extracting files of this size requires either chunked extraction or a 64-bit installer process.
Exact error from Summary.htm log (repeats 92 times per attempt):
Failed to allocate buffer for file C:\adobeTemp\ETRxxxx.tmp\34\UltraCafModels\Nano_data_1\unet_128_128_dmd\30983be4-95a8-11f0-8993-b69f465218a5.data.00 of size 1121067432
Failed memory allocation after sleep also
Extraction failed with returnCode=-1
All 4 packages fail identically: Nano_data_1 through Nano_data_4, each requiring a 1,121,067,432 byte contiguous buffer.
Additional finding: By reading the .pimx manifest files extracted from the packages, the correct installation destination was identified as: C:\Users\[user]\AppData\Roaming\Adobe\Adobe Photoshop (Beta)\AddOnModules\sensei_model_cache\inpainting_ai\ultra_caf\
Files were manually extracted using 7-Zip and placed in the correct location, but Photoshop Beta does not recognize manually placed files and continues attempting reinstallation — suggesting the installer also needs to write a completion record that it cannot reach due to the extraction failure.
