How to Fix Insufficient Memory Error for PhotoDeluxe 4 on Windows 7 64-bit
Question details
The user is attempting to run an obsolete application, PhotoDeluxe 4, on a modern 64-bit Windows 7 system but encounters a startup error.

- Product
- PhotoDeluxe 4
- Device & OS
- Windows 7 64-bit
- Scenario
- Launching a legacy 32-bit application on a 64-bit operating system.
- Observed behavior
- The software installs successfully but fails to start, displaying an 'insufficient memory' error despite the computer having 4 GB of RAM.
Verify that your Windows system recognizes your 4 GB of installed RAM via the System Properties, and ensure you have administrative privileges to adjust program compatibility settings.
Run PhotoDeluxe in Windows Compatibility Mode
Use the built-in Windows compatibility settings to emulate an older operating system, which can help legacy software properly allocate memory.
Older 32-bit applications were not designed to handle large memory capacities like 4 GB. Running the software in compatibility mode forces the operating system to present a familiar memory environment to the legacy application.
Right-click the PhotoDeluxe 4 shortcut on your desktop or the main executable (.exe) file located in its installation folder, and select 'Properties' from the context menu.
Navigate to the 'Compatibility' tab located at the top of the Properties window.
Check the box next to 'Run this program in compatibility mode for:' and select 'Windows XP (Service Pack 3)' or 'Windows 98/Windows Me' from the dropdown menu.
Click 'Apply' and then 'OK' to save the changes. Double-click the shortcut to launch PhotoDeluxe 4 and check if the memory error is resolved.

Install a Virtual Machine Running an Older OS
If compatibility mode fails, setting up a virtual machine with a legacy 32-bit operating system provides an isolated, guaranteed environment for obsolete software.
Upgrade Your Legacy Workflow with WPS Office
Obsolete legacy applications like PhotoDeluxe or older versions of Adobe Acrobat often struggle with memory errors on modern 64-bit systems. Avoid compatibility headaches by switching to WPS Office, a comprehensive, modern suite that smoothly handles all your documents and PDFs.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button.
- 2. Install the Software: Run the downloaded executable file and follow the straightforward on-screen instructions.
- 3. Open Your Files: Launch WPS Office to easily manage and edit your documents and PDFs without compatibility errors.

Frequently Asked Questions
Why does a 4GB RAM computer show 'insufficient memory' for PhotoDeluxe 4?
PhotoDeluxe 4 is an obsolete 32-bit application designed when standard RAM was measured in megabytes. On modern 64-bit systems, it miscalculates large memory capacities (like 4 GB), resulting in a false error indicating insufficient memory.
Is the PhotoDeluxe 4 memory error related to Adobe Acrobat?
While both are older Adobe products, the memory error in PhotoDeluxe is specific to its own outdated architecture. However, if you are running similarly obsolete legacy versions of Acrobat, you may experience comparable 64-bit compatibility issues.
Does Windows 7 Compatibility Mode guarantee a fix for legacy memory errors?
No. While Compatibility Mode successfully emulates older OS behaviors for many applications, programs with deeply outdated memory management might still fail on a 64-bit architecture. In such cases, using a Virtual Machine is the best workaround.
