| Problem | Solution | |---------|----------| | “Invalid product code” in Steam | You likely have a legacy retail code. Contact Sega Support. | | Key works but game doesn’t launch | Install v2.700 patch (last official) or use Steam’s verify files. | | Bought “new” from key shop but code used | That’s a scam – only buy from trusted stores. |
This is the hard path – proceed with caution.
Step 1 – Attempt Steam Conversion (Low success rate):
Step 2 – Manual Support Ticket (Higher success):
Step 3 – The No-CD Workaround (Not recommended for security):
The honest advice: If you find your 2007 Product Key in a drawer, do not spend hours troubleshooting. Spend $6 on a new Retail Code from a digital store. Your time is worth more than the friction.
To understand the difference, you must understand that Company of Heroes: Opposing Fronts (released in 2007) exists in two distinct universes. This is where the confusion between "Product Key" and "Retail Code" originates.
Do not buy Opposing Fronts alone. The smartest move is to buy Company of Heroes (New Edition) or the Company of Heroes Complete Pack on Steam.
