FAQs:
1. What is the single biggest risk of reinstalling and running QuickBooks Desktop 2015 today?
The biggest risk is data security and compliance exposure. Intuit officially discontinued support for the 2015 version, meaning:
- No Security Patches: The software receives zero updates to fix new vulnerabilities or bugs, leaving your sensitive financial data exposed to external threats.
- No Payroll Compliance: The application no longer receives updated payroll tax tables, making it impossible to accurately process federal and state payroll taxes.
- No Live Services: Online banking, credit card processing, and live support features are permanently disabled.
For long-term use, migrating your data to a currently supported version is strongly recommended.
2. Why do I need my original License Number and Product Code just to reinstall the 2015 version?
The License Number and Product Code are unique identifiers required by QuickBooks’ activation servers. Even though Intuit has discontinued live support, the software still needs to validate its licensing information to function properly after installation.
You need these codes to:
- Activate the program for the first time on a new system.
- Re-register the software after a clean installation or major system upgrade.
- Link the installation to your original purchase record for verification purposes.
If you cannot locate these codes, you must contact Intuit’s support for assistance in retrieving them from your customer account records, if available.
3. Will QuickBooks Desktop 2015 work on the latest versions of Windows and macOS?
QuickBooks Desktop 2015 was built to run on older operating systems and may encounter severe compatibility issues or fail completely on modern systems.
- Windows: While a clean install may succeed, you might face issues with data integrity or connectivity due to conflicts with newer Windows 10/11 security features and runtime components.
- macOS: QuickBooks Mac 2015 is explicitly incompatible with newer macOS versions (e.g., Catalina, Big Sur, Monterey, Ventura). Trying to run it on these systems will likely result in installation failure or program crashes. The original compatible operating systems were typically OS X 10.8 Mountain Lion to OS X 10.10 Yosemite.
4. Since online services are disabled, how can I import my old bank transactions into the 2015 software?
Because QuickBooks 2015 can no longer connect directly to banking institutions, you must rely on manual or file-based import methods.
The primary method for importing transactions is:
- Web Connect (.qbo) Files: Log into your bank’s website and manually download transaction history files in the QuickBooks Web Connect format (.qbo).
- Manual Entry: Alternatively, you must manually key in all transactions from your bank statements into the register.
Direct real-time syncing of bank or credit card feeds is permanently unavailable.
5. What specific preparation should I do before running the old installer file?
Proper preparation minimizes the risk of installation failure or data loss. Before running the installer, take the following steps:
- Backup Your Data: Ensure you have a recent, accessible backup of your existing
.QBWcompany file. - Disable Antivirus: Temporarily disable your antivirus software. Security programs can sometimes mistakenly block components needed by older installers, causing installation failures.
- Run as Administrator: Right-click the installer file and select Run as Administrator to ensure it has the necessary permissions to register components in the Windows system registry.
6. If I just need to access my old company data, which edition (Pro, Premier, Enterprise) should I download?
You must download and install the exact edition and year of QuickBooks that you used to create your company file.
- If your file was created in QuickBooks Premier 2015, you cannot open it using the QuickBooks Pro 2015 installer.
- You must also use the correct country edition (e.g., USA Edition) as files are not interchangeable between countries.
Attempting to open a file with an incompatible version will lead to an error message stating that the file was created with a different, incompatible version.
7. The download link is from a third party. Is this safe, and what should I check before installing?
Downloading unsupported software from third-party sources carries inherent risk. You should proceed with extreme caution and take these verification steps:
- Source Verification: Only use download files provided by a certified reseller, IT professional, or a reputable archival service.
- File Hashing: If possible, check the file’s MD5 or SHA-256 hash value against a known, official hash to ensure the installer has not been tampered with or infected.
- Security Scan: Run a robust, up-to-date virus and malware scan on the downloaded installer file before executing it.
If you have any doubt, contacting a certified IT professional to handle the reinstallation and data migration is the safest option.
