Important! Yahoo Finance recently changed their data access query in a way that is preventing YLoader from downloading historical data. The issue is being researched, but it's not clear that a fix will be possible

YLoader 5.0

Runs on Windows 7.1 and later and does not require a registration key.

If after installing YLoader 5 you receive an error message about missing dlls (such as MSVCP140.dll) when trying to start YLoader, download and install Microsoft Visual C++ 2015 redistributable files

Make sure to read the YLoader 5.0 release notes before installing and running the product.

YLoader 4.10 (no longer maintained!)

Runs on Windows XP and later, however it requires a registration key (see below).

YLoader 4.10 will require a registration key to run after the 14 day trial period - email us the hardware fingerprint at and we will reply with the corresponding registration key at no charge.

The hardware fingerprint is a hex string formatted as xxxx-xxxx (ex: 3AB8-F991). To get yours, start YLoader, open the About box and click on the "Enter validation key" button.

Make sure your reply email address is valid. You will receive the key usually within several hours. If you have not received it within 24 hours, check your spam folder, and if not there either, email with an alternate valid return email address (do not use the same email or most likely won't receive the second reply either).

To verify the integrity of the downloaded files, you can compare the MD5 or SHA1 cryptographic hashes listed above with the ones generated by this FCIV Microsoft utility.

Support YLoader

YLoader is released free of charge, however contributions in support of its continued development will be appreciated. Email and we will reply with the necessary information.
