Solution 1Recommended

Contact Your Microsoft CSP Provider

Reach out directly to the Cloud Solution Provider who sold you the perpetual license to get the correct deployment files.

Since CSP perpetual licenses are managed by the selling partner, the deployment files and product keys are often distributed through the partner's proprietary portal rather than the standard Microsoft 365 admin center.

1
Identify your CSP

Check your organization's purchase records, invoices, or vendor directory to find the contact information for your Microsoft partner or CSP provider.

2
Request the deployment files

Send a support request to your provider specifically asking for the 32-bit installer for Excel LTSC 2021. They will confirm if it is supported under your current agreement.

3
Obtain activation keys

Ask your CSP representative for the corresponding product keys needed for volume activation or perpetual licensing deployment, as these are required during installation.

Contact Your Microsoft CSP Provider
Deployment Tool Requirement: Your partner may provide you with an XML configuration file to be used alongside the Office Deployment Tool (ODT) instead of a direct executable download.

Frequently Asked Questions

Why can't I find the 32-bit Excel LTSC 2021 download in my Microsoft 365 admin center?

Perpetual licenses purchased through a Cloud Solution Provider (CSP) are often managed directly by the partner. This means the deployment files and product keys might not appear in your standard Microsoft 365 admin center and must be obtained from the partner.

Does Excel LTSC 2021 still support 32-bit installations?

Yes, Microsoft continues to provide 32-bit installation options for LTSC 2021. This ensures compatibility with legacy COM add-ins and older internal systems, though 64-bit is generally recommended for better performance and handling large datasets.

What is a Cloud Solution Provider (CSP) in Microsoft licensing?

A CSP is an authorized Microsoft partner that sells Microsoft cloud services and software licenses directly to customers. They often handle the billing, support, and provision of deployment files for the products they sell.

Can I use the Office Deployment Tool (ODT) to download Excel LTSC 2021?

Yes, administrators typically use the Office Deployment Tool along with an XML configuration file to download and install Excel LTSC 2021. However, you still need your CSP to verify your license and provide the specific Product ID and key.
