Photoshop 7.0 Troubleshooting

Photoshop 7.0 is limited to 2 GB of RAM on 32-bit systems (and by the 32-bit address space on 64-bit Windows). If you are opening a large PSD with many layers, try: (1) Flatten the image first in another app, (2) Increase the scratch disk space (Edit → Preferences → Plug-ins & Scratch Disks), (3) Close other applications to free RAM. Files above ~400 MB tend to be unreliable in PS 7.0.

This is usually a colour profile mismatch. Go to Edit → Color Settings and set the RGB working space to sRGB IEC61966-2.1. Make sure "Color Management Policies" is set to "Convert to Working RGB" for all three modes. Also check Edit → Preferences → Display & Cursors — if "Use Diffusion Dither" is checked, uncheck it.

Photoshop 7.0 reads fonts from the Windows Fonts folder at startup. If you installed new fonts after opening Photoshop, quit and relaunch. If fonts are still missing, the font cache may be corrupted — delete the AdobeFnt.lst file in your Windows\System32 folder (or Windows\SysWOW64 on 64-bit systems) and relaunch Photoshop.

This happens when the preview quality in Save for Web is set to "Standard" rather than "Optimised". In the Save for Web dialog, click the quality dropdown next to the JPEG setting and select "Optimised". Also make sure you are saving at quality 80 or above for print-intended images.

The Healing Brush in PS 7.0 samples from a fixed source point (Alt+click to set it). Seams appear when (a) the source area has different lighting from the target, or (b) you are healing too close to a hard edge. Try using the Clone Stamp tool near hard edges and the Healing Brush only on smooth texture areas. Reducing brush hardness to 0% also helps blend the transition.

PS 7.0 predates multi-core processors and GPU acceleration. It runs on a single CPU core only. To help: (1) Increase the memory allocation in Edit → Preferences → Memory & Image Cache to 70–80% of available RAM, (2) Increase the cache levels to 8, (3) Assign a fast SSD as the scratch disk, (4) Reduce History States from 20 to 5–10 if you have large files.

This vague error most often appears when (a) a filter is applied to an empty or locked layer, (b) the layer is in the wrong colour mode for the filter (e.g. applying a filter that requires RGB to a CMYK layer), or (c) the scratch disk ran out of space mid-operation. Check Layer → Layer Properties to confirm the layer is not locked, and Image → Mode to confirm you are in RGB mode.

Photoshop 7.0 cannot read PSDs saved with features introduced after 2002 — smart objects, adjustment layers added in CS2+, video layers, 3D layers, etc. When saving from a newer version, use File → Save As and check "Maximize PSD Compatibility" — this embeds a flattened composite that Photoshop 7.0 can open, though you will lose access to the newer layer types.
