Pro Tools 7.4 reports that it is missing critical update on Windows XP. Pro Tools will not install.
Pro Tools 7.4 requires a specific security update to be installed on your version of Windows XP in order to be installed. If your computer is missing this update you have two options.
1. Allow your computer to update using the Automatic Update feature but only allow updates dated before May 2008 to be installed. This will give you a fully updated SP2 without getting SP3.
2. Download the missing security update (KB926255) from microsoft at the link below and install it, then intstall Pro Tools.
Microsoft Secuity Update KB926255
This will only install the missing update from Sp2.
**Warning**
Sweetwater Tech Support has seen many customers having problems with third-party plug-ins and certain features of Pro Tools after upgrading to Windows XP Service Pack 3. Even though Digidesign maintains that Sp3 is fully compatible, we advise NOT upgrading to SP3 as you may experience problems with Pro Tools as a resault.
If you have upgrade to SP3, simply uninstall it and choose one of the options above.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
