Common error: “Product key has already been used”

Possible causes:

• The key was already activated on another device or profile
• A typo when entering the key
• A prior reinstall that still counts against the same entitlement

What to do if the key appears already used

Try the following:

• Re-enter the key carefully
• If you purchased from Wandlit, email support@wandlit.com with your order number — we will verify against the supplier record

Common error: “Product key is not valid”

Possible causes:

• Wrong product or edition for the key you have
• Regional or channel mismatch (e.g. wrong media)
• Characters confused (0 vs O, 1 vs I, extra spaces)

What to do if the key is reported invalid

Try the following:

• Confirm the product name on your order matches what you are installing
• Copy the key from your order email or account area instead of retyping
• Contact support@wandlit.com if the problem continues

Common error: “Unable to reach activation servers”

Try the following:

• Check your internet connection and retry
• Pause VPN or strict firewall rules temporarily
• Retry later — publisher activation services can be busy

Activation limits (typical)

Limits depend on the exact product and license channel. Typical retail examples:

• Microsoft 365 / subscription products: follow the subscription seat rules shown at purchase (not a one-time perpetual key in most cases)
• Office Home & Student / Home & Business (perpetual retail): usually one device install per license — confirm on your product page
• Office Professional (perpetual retail): typically one PC — confirm edition
• Windows 10/11 retail: one device; transfer rules depend on channel and Microsoft policy
